Question on large size 3 1/2" team pinbacks
We recently received a group of the larger sized 3 1/2" team pinbacks in consignment for our next auction and not being familiar with them I wanted to post and get a better description of them. I assume these are stadium issued, they appear to be from the late 50's thru the early 70's. No mfg. markings of any kind.
